Need help on wiring:

ABB manual states that:

"The terminals 1.8, 2.8, 3.8 amd 4.8 as wella as 1.9, 2.9, 3.9 and 4.9 are connected to each other through electric wiring and always have the same assignment indepenent of the module that is inserted:

Please look at the JPEG. Is this the wiring that the ABB states or is it that only1.8 and 1.9 needs to be supplied with 24v and 0v that will supply power to the rest of the points..

Thanks in Advance
